The Power of 'Sufficient Hydration,' More Important Than Expensive Cosmetics

My skin condition has been really bad lately, so I was worried and decided to challenge myself to drink 2 liters of water a day! I made sure to drink only pure plain water, skipping coffee or sugary drinks, and after about a week, I can definitely feel my complexion becoming clearer and my skin texture feeling firmer. Applying products to the surface is important, but I realized that hydration from within really shouldn't be underestimated. Please drink plenty of water!!
